(People's Daily health client reporter Kong Tianjiao) The new virus variant, Deltacron, recombined by Delta and Omitikorong, has been detected in several countries, including France, the Netherlands, Brazil and Denmark. Some people will ask, when the two main virus variants of Delta and Omikeron infect the same individual, what happens to the new virus variant "Delta Kerong"?
Yu Chuanhua, a professor of epidemiology and health statistics at Wuhan University, told the People's Daily health client: "There is no need to panic in the face of the new strain of Delta Kerong, the coronavirus has its own ability to recombine, mutation is a common response of the virus to adapt to human parasitism, and it is expected that the virus will continue to mutate." The new strain has not been spreading at a worrying rate since January, and there are currently no data suggesting it will spread more easily or cause more severe disease than its predecessors, so it is too early to worry too much about the new strain of Delta Kerong. ”

Yu Chuanhua explained that the World Health Organization (WHO) has recently confirmed the discovery of the New Coronavirus strain of Deltacron, which is produced by the reorganization of two strains of Delta and Omikeron, and its "backbone" is derived from Delta, but the spike protein (which allows the virus to enter human cells) is derived from Omicroon. It will have the characteristics common to two strains, Delta and Amikeron. Since it was first detected in samples taken in France in January, the new strain has also been found in the United States, the United Kingdom, the Netherlands, Denmark and other countries.
Among them, researchers at the Mediterranean Institute of Infectious Diseases in Marseille, France, published an article on March 8 saying that they confirmed the existence of Delta Kerong through genome sequencing, and the variant has been detected in several parts of France.
A new study released on March 12 by the U.S. medical research website shows that the Delta Croce variant has appeared in the United States. Since January, a U.S. Centers for Disease Control affiliated laboratory in California has detected 2 cases of Delta Kerong infection. According to the Guardian on the 11th, quoted by the British Health Security Agency, in addition to the Discovery of deltakron variants in the United States, about 30 cases of infection have also been found in the United Kingdom.
According to the covid-19 data released by the Brazilian Ministry of Health on March 15, the country has confirmed 52,094 new confirmed cases in the past 24 hours, with a cumulative total of more than 29.43 million confirmed cases. Brazilian Health Minister Cairoga said on the 15th that Brazil has confirmed two cases of new crown infected with the "Delta Kerong" strain. The infection case of the "Delta Kerong" strain was detected by the Brazilian health department during surveillance. Kairoga said that further monitoring of this new mutant strain is needed, and the current focus is on strengthening the needle for people to get the new crown vaccine, "the strengthening needle is very important."
Yu Chuanhua suggested, "The COVID-19 vaccine has been shown to be effective for the most important COVID-19 outcome, 'hospitalization, severe illness and death', even in the face of new variants." Therefore, the prevention and control measures for the Delta and Omikejong strains in the past are still effective for the new Delta Kerong strains. Continue to increase testing efforts, monitor the evolution of virus variants, and ensure that appropriate prevention and control measures are taken. The WHO also said that the COVID-19 pandemic is far from over, and we need to focus not only on saving people's lives and reducing the occurrence of serious diseases and deaths, but also on reducing the spread of the virus. ”
